They do vary but I’ll tell you how it was for me. I went down to my local AFCO (Bristol) and they gave me directions to the medical centre where my medical was taking place. I went in and told them why I was there and was given a urine sample pot to fill. Did that then eventually got called in by a nurse. Did hearing test, sight test, blood pressure, height and weight and lung capacity. Then went to the doctor where I was asked health questions (simple ones). Strip to boxers, poked, prodded and listen to my chest. She put her hands on my pelvis and I was asked to cough, then that was it. O yeah and tattoo and piercing check. Mail me if there is anything else, this was my recent medical for the RAF.
